The Self-Employed Health Insurance Deduction: Who Qualifies and How It Works

Health insurance is often one of the largest costs for a self-employed household, and the deduction can make a real difference. It is not a business expense on Schedule C. It is a deduction on the personal return, which is why rules and limits differ from what many owners expect.

Who can claim it

The deduction is available to:

• Sole proprietors and single-member LLC owners who report a net profit on Schedule C.
• Partners and members of LLCs taxed as partnerships, for premiums paid by the partnership and treated as guaranteed payments, or paid personally by the partner and reimbursed or otherwise documented under the partnership's arrangement.
• More-than-2-percent shareholders of S-corporations, when the S-corp establishes the plan and includes the premiums in W-2 wages. See S-corp health insurance for owners.

Owners of C-corporations are employees and generally receive coverage under the corporation's plan, with the corporation deducting the cost. The self-employed deduction is not the mechanism for them.

What can be deducted

Premiums paid for:

• Medical insurance.
• Dental insurance.
• Qualifying long-term care insurance, up to age-based annual limits.
• Coverage for you, your spouse, your dependents, and your children under age 27 at the end of the year, even if not dependents.

Medicare premiums (Part B, Part D, Medicare Advantage, and supplements) also qualify. Premiums for a plan you buy on a government marketplace qualify, subject to interaction with premium tax credits.

Limits and conditions

Net earnings limit. The deduction cannot exceed the net earnings from the business under which the plan is established. If the business had a small profit, the deduction is limited. Net earnings are computed after deducting the deductible portion of self-employment tax and retirement plan contributions for the owner. For an S-corp shareholder, the limit is based on W-2 wages from that S-corp.

Business must have a profit. A loss year generally produces no deduction. The disallowed premiums may still be deductible as an itemized medical expense subject to the adjusted gross income floor.

Eligible for other subsidized coverage. The deduction is not allowed for any month in which you or your spouse were eligible to participate in a subsidized health plan maintained by an employer of yours or your spouse. This applies even if you did not enroll. So if your spouse has an employer plan available at a subsidized rate, you generally cannot deduct premiums for a separate policy for those months. It can also apply to plans available through a former employer. Retiree coverage subject to specific conditions. The test is applied monthly, and eligibility for coverage of only certain family members can matter.

Plan established under the business. For sole proprietors, the plan can be in your own name. For partners and S-corp shareholders, the plan generally must be established by the entity. The arrangements for reimbursing or paying the premium and reporting it correctly are important.

Where the deduction goes

The deduction is taken on Schedule 1 of Form 1040 as an adjustment to income, which means it reduces adjusted gross income whether or not you itemize. It reduces income tax but does not reduce self-employment tax. It also can affect the QBI deduction calculation in the sense that the deduction reduces qualified business income when attributable to the business, according to specific rules.

Interaction with premium tax credits

Owners who buy marketplace coverage and receive advance premium tax credits face a circular computation: the deduction reduces income, which changes the credit, which changes the premium net of the credit that is deductible. The IRS provides worksheets and iterative calculations for this. Consider software or a professional's help, because errors can create repayment of credits.

Health Savings Accounts

If you have a high-deductible health plan, contributions to an HSA are a separate deduction, subject to limits, and the premiums of the HDHP itself count toward the self-employed health insurance deduction. See HSA for business owners.

Spouses on payroll and family coverage

If your spouse is an employee of your business, the business can offer employer-provided coverage to the spouse and family in a way that can be deductible to the business and tax-free to the employee, subject to plan rules. That interacts with the self-employed deduction. If you are a sole proprietor with a working spouse, it is worth discussing the alternatives with an adviser. See hiring family members.

Documentation

Keep:

• Premium statements and proof of payment.
• The insurance policy or plan documents.
• Records showing whom the policy covers.
• For S-corp shareholders, W-2 with premiums included in wages, and payroll records.
• For partners, partnership records treating premiums as guaranteed payments or otherwise handled according to the partnership agreement.
• Evidence of ineligibility for employer coverage in the months you claim.

Common mistakes

1. Deducting premiums on Schedule C as a business expense rather than on Schedule 1. For sole proprietors, this can be a reporting error, though the tax effect may be similar aside from self-employment tax.
2. Ignoring the earned income limit.
3. Claiming the deduction for months of eligibility for a spouse's subsidized plan.
4. S-corp shareholders not having premiums on W-2.
5. Paying a family member's premiums for someone who is not covered under the eligible category.
6. Ignoring the premium tax credit interaction.
7. Claiming deduction for premiums that were reimbursed by another source.
8. Failing to reduce the deduction by any premium tax credit.

Planning ideas

• If income is variable, consider the timing of retirement plan contributions and other deductions, because they reduce the net earnings limit.
• Compare the deduction to alternatives like employer-sponsored coverage for a working spouse.
• Consider whether an HSA-eligible plan makes sense.
• Review annually. Insurance changes, family changes, and eligibility for other coverage can alter the outcome.
